Abstract

Summary: possesses two distinct host specificity systems F1 and F2 each of which is able to restrict and modify Haemophilus phage HP1c1, while strain possesses only one system, B. Among restriction-deficient mutants isolated from strain , the rm as well as rm phenotypes for these two systems were obtained after either one or two mutational steps. The F1 system was introduced into by genetic transformation to show that the D1 and F1 systems are not allelic.
